# The Greenhouse Gas Emissions Trading Scheme Order 2020, Paragraph 95: Emission factors based on analyses


(1) The maritime operator must ensure that any analyses, sampling, calibrations and validations for the determination of emission factors are carried out by applying methods based on corresponding EN standards.
(2) Where EN standards are not available, the methods must be based on suitable ISO standards or national standards.
(3) Where no applicable published standards exist, suitable draft standards, industry best-practice guidelines or other scientifically proven methodologies must be used, limiting sampling and measurement bias.
(4) The result of any analysis must be used only for the delivery period or batch of fuel for which the samples have been taken, and for which the samples were intended to be representative.
(5) When determining a specific parameter, the maritime operator must use the results of all analyses made with regard to that parameter.
